HAULING DEVICE FOR AGRICULTRAL MACHINES.

specification gf Leiters raient. Patented July 21, 19ML Application filed March 9, 1914. Serial No. 823,499.

To all whom it may concern 1 Be it known that l, VVLADIMIR voN ltnczrivsnr, a subject of the Emperor' of Germany, and residing at 20 AVVilhelmstrasse, Posen, Germany, have invented certain new and useful Improvements in Hauling Devices for Agricultural Machines, of which the following is a specification.

vThe invention has reference to improvements in power driven portablezhauling devices driven by internal combustion engines for operating agricultural machinery such as plows.v

As is well known, combustion engines, or Diesel engines, or the like, are, as normally constructed, not well adapted for taking overloads. It is therefore, contrary to the case with steam engines, necessary to put the load on to such engines always very gradually by means of friction clutches. In this manner, however, the amount of time wasted is increased to an impermissible degree, and, when the clutch is switched in carelessly, very considerable diliculties and delays in the working may be caused, which it is absolutely essential to avoid in powerdriven plowing, quite apart from the fact that the wear andv tear of the clutches, which, in view of the high power required for the rapid shifting onward of the portable haul ing device are very heavy and expensive, is yvery great owing to the frequent employment of said clutches. i

It has already been proposed, to provide a. steam portable hauling device for operating plows with an extra gear for propelling it along at a slower rate when it has to be moved on bad ground, besides the usual traveling gear, and to put this extra gear for the slow speed into act-ion, for the purpose of saving time, while the windingdrum is still revolving during the latter part of the travel of the plow toward the hauling device, so as to move the hauling` device onward to the ext-ent of the width of one furrow.

In view of that which has been set forth above with regard to hauling devices with explosion engines, it will be clear that also the last mentioned arrangement is notsuitable for this class of hauling devices, namely,`those with explosion engines. l By the present invention, however, the practical employment of portable hauling devices for operating plows with explosion engines is rendered possible by the fact that, instead of the device being provided with the abovev mentioned slow-speed traveling gear, it is provided with av gear which is of such high y ratio, z'. e. it gives such a slow speed of travel, that it cannot come into question at all for traveling purposes on roads, but is on the other hand .capable of propelling the hauling device laterally during the whole plowing operation at an almost imperceptible speed. If one t-akes, forexample, a lield 250 yards in length, fthe engine will move laterally to the extent of one furrows width, or say 2 yards, which corresponds to a rate of progression of about ins. per sec.

with the invention. Fig. 2 is a plan of the partsshown in Fig. l, and Fig. 3 .is a rear sectional elevat-ion of part of thedevice shown in Fig. l, drawn to a larger scale.

Referring to the drawings the engine shaft p driven by the engine (not-shown) is provided with three slidable gears g each of which is capable of enmeshment with one of the three gears r upon the intermediate shaft s carrying the bevel pinion m. The cable drums d and e are driven oft1 this inter mediate shaft s by means of the bevel pin* ions t, shaft c and pinion o which is slidable in a. verticaldirection so that it can mesh with the peripheral teeth of either of the aforesaid drums. lt will be seen from Fig. 3 that the pinion fo does not drive the drums CZ and e simultaneously but is slidable along the shaft c to mesh with the drums Z and e alternately. @ne o-f the bevel gears t is slidable along its shaft and is moved out of enmeshment with the other bevel pinion t while the machine is traveling on the road.

The tractor wheels a and o are driven offr the intermediate shaft through bevel pinions m, Z, and 7c; the pinion fm, is iixed on the end of the shaft .g whereas the pinions c and Z are slidable on the shaft z' and only one of these pinions is in mesh with the pinion m if the machine is traveling on the road. For traveling in a. forward direction the pinion Z meshes with the pinion m, and for traveling in a backward direction the pinion Ze meshes with the pinion my. The drawing shows the machine in the field and therefore neither of the pinions 7c or Z is in mesh with the pinion m but the pinions t are in mesh with each other. The pinions 7c and Z are mounted on a shaft c' at the other end of which yis mounted a pinion o gearing with a spur wheel y'w on the shaft which has mounted thereon a small pinion g/ gearing with the spur wheel e rigidly mounted on axle of the wheels n and o. A lantern wheel b is mounted on the shaft z' and normally engaged by a pawl ZL mounted on a swinging lever g to the lower end of which is attached the arm adapted to beactuated by the trip or cam ct on the shaft c. The pinion m is not in mesh with the wheel Ze or Z but the pinions t are in mesh and therefore the shaft c is rotated driving alternately the drums CZ and c. During each revolution of the shaft e the lever g is swung back and forth and the pawl ZL thereby rotates the wheel to the extent of one tooth. If for instance the wheel has 8O teeth the shaft z' makes one revolution while the shaft e makes 30 revolutions so that a very slow and steady progression is effected.

Having now described my invention what I claim as new and desire to secure by Letters Patent is l. A power driven portable haulino` device for operating agricultural mac lines such as plows comprising in combination with the traction wheels of means including an internal combustion engine for driving said wheels at a uniform speed such that the hauling device will move slowly through a predetermined distance.

2. A power driven port-able hauling de- Vice for operating agricultural machines moving over a plurality of courses in a field, comprising in combination with the traction wheels7 of means including an internal combustion engine for driving said wheels at a uniform speed over a distance equal te one of the courses in the iield during the time that the agricultural machine or machines completes a course in said field.

3. A power driven portable hauling device for operating plows comprising in combination with the traction wheels, of means including an internal combustion engine for driving said wheels at a uniform speed to the extent of one furrow during the period `of time taken by the plow to plow a furrow.

et. A. power driven portable hauling device for operating plows comprising a conu tinuously operating internal combustion engine and reduction. gearing for causing said engine to drive the hauling device at an eX tremely low operating speed.

in testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
